► Develop a Degradation-Threshold-Shock model with dependent failure modes. ► Propose the maintenance policies with time-based and condition-based minimal repair. ► Develop the mathematical cost models of these maintenance policies. ► Compare and discuss the performances of each minimal repair appro...
